<sect4><title>libc, libc_nonshared</title>
|
|
<para>These files constitute the main C library. The C library is a
|
|
collection of commonly used functions in programs.
|
|
This way a programmer doesn't need to create his own functions for every
|
|
single task. The most common things like writing a string to the screen
|
|
are already present and at the disposal of the programmer.</para>
|
|
|
|
<para>The C library (actually almost every library) comes in two flavors:
|
|
a dynamic and a static one. In short, when a program uses a static C
|
|
library, the code from the C library is copied into the executable file.
|
|
When a program uses a dynamic library, the executable will not
|
|
contain the code from the C library, but instead a routine that loads
|
|
the functions from the library at the time the program is run. This
|
|
means a significant decrease in the file size of a program. The
|
|
documentation that comes with the C library describes this in more
|
|
detail, as it is too complicated to explain here in one or two
|
|
lines.</para></sect4>

<para>The basic idea is to put the implementation of the different services
|
|
offered to access the databases in separate modules. This has some

advantages:</para>

GNU C library,</para></listitem>
